Title: Puzzles
Inventor: BLACKBURN DAVID
IPC: A63F9/08
Filed: 1991-08-12
Abstract: A puzzle has a cube cage 12, of a volume N cube playing pieces, containing an assembly of N-1 cube playing pieces thus leaving a void in the cage. The cage has apertured walls to enable the pieces to be sequentially moved into the void. The surfaces of the pieces carry markings. In one position of arrangement of the pieces the markings expressed on each external surface of the assembly form a complete image, and the pieces can be re-arranged to form different exposed complete images e.g. pictures, graphics, patterns. The cage may take various shapes and the pieces may be rotatable as well movable into the void. <IMAGE>
Patent GB-2260053-A (GB)
Title: Image signal processing in full frame format
Inventor: HEDLEY DAVID JOHN
IPC: H04N5/44
Filed: 1991-09-27
Abstract: An image signal processing system is described in which image data in an interlaced format is converted to full frame format prior to application of any vertical processing. A swing buffer 40 is employed with Field 0 being written into the even addresses of a DRAM 44 forming one side of the swing buffer under control of a write controller 48. Field 1 is written into the odd addresses. The data in full frame format is read from consecutive addresses in the DRAM 44 into a signal processing engine 62 whilst the next frame is being written into the DRAM 46 forming the other arm of the swing buffer 40. This arrangement allows data that was captured in full frame format to be vertically processed in full frame format thereby preserving its vertical resolution. The full frame image data was converted to interlaced format prior to receipt by the image processing system for compatibility with hardware developed for interlaced format data. <IMAGE>

Title: Remote maintenance of a private branch exchange system
Inventor: KIM YANG-SEON
IPC: H04Q3/62
Filed: 1992-03-02
Abstract: A PBX system 200 is maintained by connecting the system with a remote maintenance center 220 through a public switch telephone network (PSTN). State information about the PBX system is transmitted to the remote maintenance center 220 by connecting a remote maintenance connection circuit 210 automatically when the PBX system receives an incoming call from the remote maintenance center 220. A MODEM control circuit (302. Fig. 3) communicates the state information with an external modem 221 by utilizing a MODEM (303, Fig. 3) built in the system, without using a separate port. Maintenance, including function change, can be carried out remote from the PBX so a technician's visit is not necessary. <IMAGE>

Title: Process for the separation of radioactive iodine compounds by precipitation
Inventor: OCHIAI KEN-ICHI
IPC: G21F9/06
Filed: 1992-11-02
Abstract: A process for the separation of radioactive iodine compounds by precipitation comprises adding 0.1 to 3 parts by weight of a reducing agent such as sodium sulphite of hydrogen sulphite and an effective amount of silver nitrate to 100 parts by weight of a liquid waste containing radioactive iodine compounds while keeping the liquid waste at a temperature ranging from 20 to 80 DEG C, and stirring the obtained mixture for 0.5 to 72 hours to precipitate the radioactive iodine compounds. Silver nitrate is preferably used in a molar concentration which is 1 to 4 times that of radioactive iodine molecules contained in the liquid waste. By this process, iodates which could not be precipitated by conventional methods can be effectively precipitated and separated thereby reducing the amount of radioactive iodine discharged to the environment.

Title: Contact prevention system for a backhoe
Inventor: MIURA KEISUKE
IPC: E02F3/43
Filed: 1993-11-04
Abstract: This backhoe includes a detecting device for detecting a position, direction and velocity a bucket 6 relative to a drivers section 27, and a control device for controlling a boom assembly 3 based on detection values provided by the detecting device. The control device has a function to prohibit operation of the bucket when the bucket moves inwardly of a danger plane A1 orA2 disposed at a predetermined distance outwardly of the drivers section. The control device establishes a caution plane C1 or C2 disposed at a predetermined distance outwardly of the danger plane A1 or A2, and has a time estimating function which, when a bucket pin 6a lies in a danger zone B1 or B2 defined by the danger plane and caution plane, computes and estimates time taken for the bucket 6 to reach the danger plane A1 or A2. To realise an ideal decelerated motion, a set time is determined in advance by using a horizontal distance to the danger plane A1 or A2 as a variable. The control device has a decelerating function to decelerate operation of hydraulic cylinders so that the set time and the time estimated agree. <IMAGE>

Title: An engine mount assembly having a one-piece moulded support
Inventor: TOURNIER PASCAL
IPC: F16F13/14
Filed: 1996-09-25
Abstract: An engine mount assembly comprises a rigid generally cylindrical member 14 for attachment via an armature 10 to a chassis or body of a vehicle. A central rigid metal insert 20A is bolted to an engine and is supported by a one-piece moulded support 22 made of resilient material, eg rubber. The support 22 defines a working chamber 62 which is connected to two interconnected compensating chambers 42, 44 via a restricted-flow conduit 64, 66 for damping transfer of hydraulic fluid and thus damping vibrations. High frequency vibrations cause a flexible membrane 60 to vibrate in a space defined between a rigid apertured plate 58 and an apertured part 56 of the cylindrical element 14. The apertures 56 expose the membrane 60 to atmospheric pressure. Abutments 46, 50 are mounted within compensating chambers 42, 44 to limit transverse vibration. The fluid within the compensating chambers 42, 44 and the grooved outer surfaces of the abutments 46, 50 reduce their effect on vertical vibrations.

Title: laser device
Inventor: DUGGAN GEOFFREY
IPC: H01S5/183
Filed: 1996-12-21
Abstract: A separate confinement heterostructure (SCH) laser device (LD) has a quantum well active region 10 within an optical guiding region 12, and n- and p-type cladding regions 14 and 16 on opposite sides of the guiding region 12. An electron-capture layer 36 is provided in the n-side guiding region 12a. The composition of the electron-capture layer 36 is such that the minimum energy for X-electrons in the conduction band is lower than that in the surrounding parts of the active region 10 and/or the n-side guiding region 12a. The electron-capture layer 36 is thick enough to bind X-electrons so that, in use, the electron-capture layer 36 promotes the capture of X-electrons. The electron-capture layer 36 is sufficiently close to the active region 10 to permit transfer of captured X-electrons to at least one #-confined level in the active region 10.
